Improvement in dye-tubs



tzend @dus THOMAS SAMPSON, OF PROVIDENCE, RHODE ISLAND.

Letters Patent No. 109,059, dated November 8, 1870.

IMPROVEMENT IN DYE-TUBS.

I The Schedule referred to in these Letters Patent and making part of the same.

`To all whom it Imay concern:

l Be it known that I, THoM/AsSaMrsox, of the city and county of Providence, inthe State of Rhode Island, have invented a new and improved Dye-Tub and I do hereby declare that the following specifica tion, taken in connection with the drawing making a part of the same, is a full, clear, and` exact description thereof.

Figure l is a top view, with reel removed.

Figure 2 is a cross section.

Figure 3 is an elevation, opposite corner.

The object of my invention is to so construct a dye,

tub that the operation of dyeing the clot-l1 may be more easily and at thc same time more thoroughly performed, and consists in the device for that purpose hereinafter described.

The ordinary dye-tub now in use is a plain square or rectangular tub,.provided with a reel and steampipes in a manner well understood, in which the dye is prepared and the cloth run in.

The great difficulty experienced has been-the tendency of the cloth to' twist and knot, thus rendering it impossible for the dye to act evenly upon all portions of it. To overcome this diiculty meu are. usually employed to open the cloth while in the tub by means of sticks or poles, which operation is only B, theformer being'preferahie, extending from the l top 'nearly to thepoppositc side and also with a coinpartinent, C, having its lside nearthe partition B of wire gauze, within which the dye is placed.

(t and a' are steam-pipes, running across anzi to the top of' the tub. I

The operation of my invention is as foilows:

The tub being provided with the requisite amount of liquid, the end of the cloth is placed upon the reel and the reel started in the proper direction. As the cloth descends intothe tub it strikes against the curved part A, which lays it in smooth folds, and prevents it from knoting or twisting iu such a manner as to render less effective the action of the dye. ",Ihe cloth, by the accumulated weight ofthe successive folds, is forced into the liquid, the partition B preventing it from coming to the surface until it has passed through t0 the partition l1), which' protect-s the cloth from the steam-pipe c, when lit is drawn up fo the top and the ends ofV the clot-h united, thus for-.ming a continuous band, which is carried by the reel through the dye uutl the color is complete.

W'hat I claim as my invention, and desire to secure by Letters Patent, is-

'1. A dye-tub, having a. partition, B, arranged in the manner substantially asdescribed, for the purposes specified. Y

2. A dye-tub, having a parti-tion, l, in combination with a compartment, C, the whole constructed and arranged in the manner substantially as described.I
